I APERI-SHEET-GLUING MACHINE.

Specification of Illetters Patent.

Patented Apr. 8, 1913.

Application filed Kay 29, 1911. Serial No. 630,199.

To all wkom it may concern Be it known that I, WALTER KELLNER, of

Wiescherstrasse 13, Barmen, Rhenish Prussia, Germany, have invented .newand useful Improvements in Paper-Sheet-Gluing Machines, of which thefollowing is a full, clear, and exact specification.

My invent-ion has reference to machines by which a sheet of paste-boardand a sheet of paper or textile fabric are glued together, thepaste-board being transported on a table and the covering sheet guidedover a roller to be fed with glue and then are carried to meetthepaste-board forbeing united therewith. Now in order to obtain afabric without folds and wrinkles and With a smooth surface I haveconstructed my machine in such a manner that the glued covering sheetwhich on its way to the meeting point with the paste-board is supportedon an endless transporting band of textile fabric with the glued surfaceoutward travels a long way during which the paper sheet may be thoroughly impregnatedor get moistened and at the same time is .firmlypressed down or drawn on the said transporting band, so that no foldsand wrinkles can be formed and the sheet may be smoothly pasted on thepaste-board.

In order to make more clear my invention I have illustrated the same onthe accompanying sheet of drawing, showing the apparatus in its main oressential features.

Referring to the drawing the numeral 0. indicates a table supporting thesingle sheets of paper or the like which'should be pasted on thepaste-board, that is placed in single sheets on a second table it beingarranged above the table a as shown. In front of said table a a pair ofrollers b is situatedwhich receive the single paper sheet or blank andguide it to and upon the surface of the glue feeding roller e'. Saidroller e is in more or less close contact With'a roller 6 that dips intoa receptacle e filled with glue. By means of the said roller e the blankis provided on its surfacewith glue and then it isfreedfrom said rollerby means of a fork or the like instrument (2 and turned the. gluedsurface upward and laid uponan endless belt f of textile fabric. Saidbelt is supported by an inclined table 71 having arranged at both of itsends the rollers 73 i respectively and underneath of its bottom a rolleri said three rollers serving as a guide for the said endless belt f. Theroller 2' cooperates with a roller 9 and these rollers i and g arelocated in front of the table it as shown. The side portions of the roombetween the bottom of the table a and the botthe other end during whichtravel the blank may be thoroughly moistened or impregnated with themoisture of the glue so that afterward no folds can get in the blank andto further improve this action the blank is by, means. of the suckingaction of the fan 7: which is exerted through the holes i of the table2' and the textile fabric of the belt smoothly forced or drawn down'onthe belt f and by this means both blanks the pasteboard 1' and the sheet1' when passing the rollers. i 9 are firmly united together and thefirst one lined with the sheet ina manner that not a bit of a fold orwrinkle appears on its surface.

I declare that what I claim is:

1. In a paper gluing machine, means for applying glue to the under sideof a sheet, means coacting with the gluing nieans for inverting thesheet, a conveyer on which the inverted sheet is carried into contactwith a second sheet, suction means for firmly holding the sheet on theconveyer, and means for pressing the two sheets into unison.

2. A sheet gluing machine comprising means for applying glue to a sheet,a conveyer on which the sheet is carried with its glued side up, suctionmeans coacting with the conveyer for holding the sheet firmlyv WALTERKELLNER. [L. s.]
